Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating covering material for covering an outer peripheral surface of a duct, for example.

[0002]

2. Description of the Related Art Conventionally, in order to heat-insulate a duct, innumerable tack terminals are fixed to each surface of the duct with an adhesive.

Next, a sheet-shaped heat insulating member cut to the width of each surface of the duct is superposed on each surface of the duct, and a planting tack is pierced into the heat insulating member.

After that, a washer is fitted on the tip of each tack, and a heat insulating member is attached to each surface of the duct through the tack by bending the tip of the tack.

Then, each seam of the heat insulating member is pasted with an adhesive tape such as an adhesive tape.

[0006]

When the above-mentioned method is adopted, it takes a lot of time to find the fixed position of the tack when the tack is planted in the duct, and the work is difficult because the space at the site is narrow. become.

[0007] Also, when piling up the heat insulating member on the duct while piercing the heat insulating member with the nail-shaped rivet, the rivet member cannot be seen due to the heat insulating member, so care must be taken not to pierce the tip of the rivet member in the hand of the operator. I have to. Therefore, the heat insulating members cannot be stacked quickly.

Furthermore, since the work of bending the tips of the tacks is performed in a narrow space on site, there is a problem in that workability is poor.

Therefore, the present invention is designed to significantly improve workability.

[0010]

In order to solve the above-mentioned problems, the present invention is a plate-like and foldable heat insulating member having a predetermined width and length, and a porous end of the back surface of the heat insulating member. And a washer fitted to the end of the tack so as to form a predetermined gap between the facing surfaces of the heat insulating member and the mounting plate. A washer fitted on the tip side of the tack protruding from the surface of the heat insulating member, an engaging portion formed by bending the tip of the tack so as to engage with the surface of the washer, and the heat insulating member A heat-insulating covering material comprising a protective sheet adhered to the entire surface of the sheet with an adhesive is used.

[0011]

In the covering material having the above-mentioned structure, the covering materials are superposed on the surface of the duct while fixing the respective mounting plates to the surface of the duct via the adhesive.

An adhesive tape is attached to the surface of the butt seam of the covering material, and the surface is affixed.

The mounting plate fixed to the duct via an adhesive is
A part of the applied adhesive passes through the hole, spreads like a harpoon in the gap between the washer formed by the washer and the heat insulating member, and hardens.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a foldable plate-shaped heat insulating member 1 having a predetermined width and length has nail-shaped tacks 3 having a porous mounting plate 2 at a terminal thereof in a predetermined arrangement. (For example, the distance between them is 300 mm pitch).

Glass wool or the like is used for the heat insulating member 1, and the porous mounting plate 2 is provided with a plurality of through holes 4 at each side edge of the rectangular plate-shaped body in the illustrated case.

Further, the washer 5 is fitted on the tip of the tack 3 penetrating the heat insulating member 1, and the tip of the tack 3 is bent so as to engage with the surface of the washer 5 to provide the engaging portion 6. .

Further, a washer 7 is formed at the end of the tack 3 to form a predetermined gap between the facing surfaces of the mounting plate 2 and the heat insulating member 1.
Is fitted.

The washer 7 is formed by bulging the central portion in the shape of a plate in the one-sided direction, and a gap is provided between the peripheral edge of the surface of the washer 7 and the peripheral edge of the mounting plate 2.

On the entire surface of the heat insulating member 1, a protective sheet 9 having fire resistance such as aluminum foil is attached via an adhesive 8.

The covering material having the above-mentioned structure is covered so as to overlap the entire surface of the duct 21.

As shown in FIG. 3, as the covering material, one piece is used to cover the entire surface, or one covering surface, or two or three surfaces at a time, and the remaining one surface. Yes, two cuts 22 are formed inward from the back surface of the heat insulating member 1 on the back surface of the cover material in contact with the corner of the duct 21, and the heat insulating member 1 between the cuts 22 is removed (see FIG. 2). As shown)
Providing the cutout portion 23 facilitates bending.

Further, the seams where the covering materials are butted are pasted together using an adhesive tape 24.

When attaching the covering material, each mounting plate 2 is fixed to the duct 21 via the adhesive 25.

The adhesive 25 applied to the duct 21 goes through each through hole 4 toward the side surface of the mounting plate 2 in the protruding direction of the tack 1, and spreads like a harpoon to cure. That is, since a gap is provided between the mounting plate 2 and the heat insulating member 1 by the washer 7, it becomes easy for the mounting plate 2 to flow out to the side surface of the heat insulating member 1 through the through hole 4.

[0026]

[Effect] Since the covering material of the present invention is configured as described above, it is necessary to pierce a tack in a narrow space on site,
There is no need to bend the ends of pierced rivets or attach sheets. Therefore, the working time can be significantly shortened.

Further, a through hole is provided in the attachment plate of the tack, and
Since a gap is provided between the mounting plate and the heat insulating member by the washer, the adhesive that spreads on the plate surface of the mounting plate through the through hole becomes like a harpoon. For this reason, the attachment plate is prevented from falling off from the duct.
